2. Filter characteristics scale with output sample rate.
3. The analog modulator samples the input at 5.6448 MHz for an output sample rate of 44.1 kHz. There is
4. Group delay for Fs = 44.1 kHz, t
no rejection of input signals which are multiples of the sampling frequency (n × 5.6448 MHz ±20.0 kHz
where n = 0,1,2,3...).
